COTTON-SEED DELINTER AND GIN.

Specification of Letters Patent.

Application flled March 6, 1911. Serial No. 612,510.-

panying drawings, forming part of this specification.

Our invention relates to a cotton seed delinter which may be adapted foruse as a gin-by a slight adjustment of the parts.

Our invention also relates to the particular manner of forming thetoothed rolls for use in such delinter and gin.

'Our invention also relates to various other novel features and detailsof construction all of which are described in the followingspecification and pointed out in the claims annexed hereto.

In. the accompanying drawings which illustrate one form of apparatusmade in accordance with our invention, Figure 1 is a vertical crosssection; Fig. 2 is an enlarged detailed view of one of the blades ofwhich the rolls are formed; Fig. 3 is a longitudinal section through oneend of one of the rolls and the parts adjacent thereto; Fig. 4 is anelevation on a reduced scale of one end of the apparatus; Fig. 5 is anenlarged sectional view showing a detail of construction; Fig. 6 is avertical longitudinal section through the center of the apparatus; Fig.7 is an enlarged detailed view of a portion of one ofthe rolls and Fig.8 is an elevation looking at the opposite end from Fig. 4.

Like marks of reference refer to similar parts in the several views inthe drawings. 10 represents the casing of the machine. This casing 10 isprovided at its ends with frame-work 11. Slidingly mounted upon theframe-work 11 are boxes 12 in which are journaled shafts 13 upon whichare mounted the toothed rolls which will be hereinafter described indetail.

In order to adjust the rolls toward and away from each other thebearings 12 are provided on their lower faces with lugs 14 engaged byscrew-threaded rods 15 provided at their outer ends with hand wheels 16.Arranged between the two rolls is a double concave 17 carried upon across bar 18. This cross bar 18 is supported at its ends byscrew-threaded rods 19 carried in lugs 20 on the frame-work 11 andprovided with hand wheels 21, by means of which they may be turned toraise and lower the bar 18 and thus adjust the concave 17 toward andaway from the rolls. Arranged directly below the concave 17 within thecasing 10 is a receiver 22 for the cotton seed. This receiver 22 ispreferably provided at its bottom with a spiral conveyer 23 fordischarging the cotton seed from the machine through a spout 24, asshown in Figs. 4 and 6. The conveyer 23 may be driven by a pulley 25mounted upon its shaft, as shown in Fig. 6.

In order to feed the cotton to the rolls we arrange between the upperparts of the rolls a float shaft 28 provided with blades 29 andjournaled in bearings 30 carried by the frame-work 11. The float shaft28 may be driven by means of a pulley 31 upon the said shaft, as shownin Figs. 4 and 6. Arranged directly above the float shaft 28 is a hopper32 provided at one side with a large sliding door 33 and at the otherwith smaller sliding door 34. These sliding doors 33 and 34 allow ahinged cover 35 to be thrown either into the position shown in fulllines in Fig. 1 so as to separate the hopper from the float shaft 28 orinto the position shown in dotted lines, so as to allow the material tobe fed from the hopper to the float shaft. At each edge of the cover 35the apparatus is provided with a downwardly projecting portion 36 towhich is secured a blade 37. This blade 37 is secured in position bymeans of screws 38 passing through slots 39, as shown in Fig. 5 so thatthe said blade 37 may be adjusted toward and away from the toothedrolls.

The construction of our toothed rolls will now be described in detail.Each of the r olls consists of a pair of cylindrical end I pieces 40, asshown in Figs. 3 and 6. Carried by these end pieces 40 are a number ofrods 41 upon which are mounted blades 42. These blades 42 are shown indetail in Fig. 2. Each of the blades are provided at opposite sides withteeth 43 formed of the arc of a circle and at each end the blade isprovided with a recess 44 adapted to engage with the rods 41. The bladesthus overlap as is best shown in Fig. 7 and spaces 45 are left betweenthe blades for the passage of air to disengage the cotton from theteeth. The roll being'built up of these blades 4 2 1s hollow in itsinterior and the air contained therein will be forced out through thepassages 45 by centrifugal force so as to disengage the cotton from theteeth. In order to regulate the flow of air through the passages 45 weprovide the end pieces 40 with disks 46 provided with openings 47adapted to be brought into registry with openings 48 1n the end pieces-40. These disks 46 are secured in position by means of screws 49passing through slots 50 in the end pieces 40, as shown in Fig. 6, sothat the said disks may be rotated to bring the openings 47 into or outof registry with the openings 48 so as to'regulate the flow of air intothe interior of the rolls. The rolls are driven by means of pulleys 51mounted upon the shafts 13.

In order to feed the cotton to the rolls when. the cover 35 is in theposition shown in Fig. 1, we provide at one end of the hopper 32 a chute52, as shown in Fig. 6, and mount upon the end of the float shaft 28, aworm wheel 53 adapted to feed the cotton seed in the direction of thelength of the float shaft 28 and the main rolls.

The operation of our apparatus is as follows: WVhen it is desired to usethe apparatus-as a gin the concave 35 is thrown back into the positionshown in dotted lines and the cotton is fed into the hopper 32. Thecotton wraps around the float shaft 28 as it is rotated and thus forms aroll which is presented against the teeth of the ginning rolls. Theblades 37 are so adjusted as to prevent the passage of the cotton seedbetween themselves .and the toothed rolls. The double concave 17 isadjusted to such a distance from the toothed rolls as to allow thecotton seed covered by the short cotton fiber to pass down into thereceiver 22. The cotton separated from the seed by the action .of theteeth 43 will be blown from the teeth by means of the current of airpassing between the blades and will be deposited in the main casing 10.Inasmuch as our rolls are provided with fiat teeth and the teeth do notpass between slots as in the ordinary gin, our gin does not injure thefiber of the cotton.

When it is desired to use the apparatus as a cotton seed delinter thecover 35 is moved into the position shown in full lines in Fig. 1 thusclosing the hopper 22. The cot-ton seed containing the short fiber isnow fed down the chute 52 and is forced along the float shaft 28 bymeans of the worm 53. When the apparatus is used as a delinter thedouble concave 17 is raised until it is so close to the toothed rollsthat the cotton seed can only pass between the two parts when all thefiber is removed.

The blades 42 forming the toothed rolls of our apparatus may be stampedout of sheet noa vsv steel and afterward hardened. In this way a verycheap and comparatively light roll is formed. At the same time theblades after becoming dull on one side may be reversed thus practicallysecuring two rolls for. the cost of manufacture of one.

Having fully described our invention what We claim as new and desire tosecure by Letters Patent of the United States, is:
